Thanks for all your suggestions. Emmy is doing better--no more "rea", thank goodness! I went back to mixing the puppy and adult food together (more adult than puppy). At first neither Emmy or Oscar wanted it. I think Oscar was getting attached to the wet food I was giving him. I let him finish the can of wet by mixing in a little bit of kibble. Last night and today they have both been eating the mixed kibble--adult and puppy. I did not give them any other options! I tried putting the same food in two bowls, but they won't eat out of but one bowl!!!

funny little dogs (Bowls are identical, BTW).
I went grocery shopping earlier (AARG!!!). While there I bought a carton of plain yogurt for them to try. I gave each about 1 1/2 teaspoons in two small bowls. I could have put the bowls back in the cabinet without washing them, they were so clean! (but I didn't, I put them in the dishwasher). They loved it...kept thinking they were going to get some more--little buggers!
Once more, thanks for your suggestions....
